KNX – the Worldwide STANDARD for Home and Building Control
In order to transfer control data to all building management components, a system is required that does away with the problems of isolated devices by ensuring that all components communicate via one common language: in short, a system such as the manufacturer and application domains independent KNX Bus.
The KNX standard is based upon more than 24 years of experience in the market, amongst others with predecessor systems to KNX: EIB, EHS and BatiBUS. Via the KNX medium to which all bus devices are connected (twisted pair, radio frequency, power line or IP/Ethernet), they are able to exchange information.
Bus devices can either be sensors or actuators needed for the control of building management equipment such as: lighting, blinds / shutters, security systems, energy management, heating, ventilation and air-conditioning systems, signalling and monitoring systems, interfaces to service and building control systems, remote control, metering, audio / video control, white goods, etc. All these functions can be controlled, monitored and signalled via a uniform system without the need for extra control centres.

The Z-Wave protocol is an interoperable, wireless, RF-based communications technology designed specifically for control, monitoring and status reading applications in residential and light commercial environments. Mature, proven and broadly deployed (with over 70 million products sold worldwide), Z-Wave is by far the world market leader in wireless control, bringing affordable, reliable and easy-to-use ‘smart’ products to many millions of people in every aspect of daily life.

EnOcean modules combine micro-energy converters with ultra-low power electronics and reliable wireless communications. This enables EnOcean customers to create self-powered wireless sensor solutions that are fundamental for collecting and processing data in an intelligent system.The specific characteristics of this protocol allow highly energy-efficient communication.
Since most energy harvesters deliver only very small amounts of power, it is necessary to accumulate it over time while the system is sleeping and to lose only a small fraction of it in the process. Therefore EnOcean sensors have an extremely low idle current. This means that only a very tiny amount of energy is consumed while the system is sleeping. The latest generation of EnOcean energy harvesting wireless sensors requires standby currents of only 100 nanoamperes (nA) or less.
